INDIANA, Pa., July 28 /PRNewswire-FirstCall/ -- Superior Well Services, Inc. (Nasdaq: SWSI) ("Superior"), Indiana, PA, and Marathon Oil Corporation (NYSE: MRO) ("Marathon"), Houston, TX, have entered into a multi-year, non-exclusive license agreement for the EXCAPE((R) )Completion Process, effective July 1, 2009. The EXCAPE((R) )Completion Process, developed and patented by Marathon, is a total system concept that can increase reserve potential by strategically targeting discrete pay intervals. This unique technology in basic form consists of perforating guns mounted outside the casing and integral valves inside the casing for zonal isolation. All equipment is remotely actuated without wellbore intervention to facilitate the rapid, pin-point stimulation of reservoir sections.

Dan Arnold, Superior's Vice President of Sales and Marketing stated "Superior is excited about the EXCAPE((R) )Completion Process and especially the new tools that we expect to be continually added to this technology portfolio. We believe Superior's participation with the development team member companies will bring expanded use of these systems within the oil and gas industry. This technology requires less well intervention during the completion process. It therefore reduces the amount of exposure to potential injury of not only Superior's people, but all the people on location. We believe enhanced technologies that also have safety benefits are of value to all of us, and we intend to help champion the EXCAPE((R) )Completion Process."

Superior has operating locations across the U.S. and is well positioned to provide high-quality cementing and fracture stimulation services in support of EXCAPE((R) )installations and completions for Marathon and other customers. Superior believes that Marathon's selection of Superior for the EXCAPE((R) )Completion Process will reinforce Superior's reputation as a leading provider of well site solutions across the U.S.
